ICD-10 Codes MCP

Anthropic-published MCP server distributed via the anthropics/healthcare plugin marketplace. Exposes the International Classification of Diseases, 10th Revision (ICD-10) — both diagnosis (ICD-10-CM) and procedure (ICD-10-PCS) codes — for medical coding, billing accuracy, and claims management. Underlying data is published by CMS and the CDC.

How to install

  • Claude Code — plugin marketplace (recommended):

    /plugin marketplace add anthropics/healthcare
/plugin install healthcare@healthcare

    The ICD-10 MCP now ships as one of the connected MCP servers inside the consolidated healthcare plugin (the older standalone icd10-codes@healthcare plugin is deprecated upstream). The server is a hosted HTTP endpoint at https://hcls.mcp.claude.com/icd10_codes/mcp.

  • Claude Code — direct MCP add (without the plugin):

    claude mcp add --transport http icd10-codes https://hcls.mcp.claude.com/icd10_codes/mcp

  • Claude Desktop — Desktop has no native HTTP transport; proxy the hosted endpoint via mcp-remote:

    {
  "mcpServers": {
    "icd10-codes": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://hcls.mcp.claude.com/icd10_codes/mcp"]
    }
  }
}

What it does

Wraps ICD-10-CM and ICD-10-PCS code sets with MCP tools that let Claude:

  • Look up a diagnosis or procedure code by ICD-10 identifier.
  • Search the code set by clinical term, body system, or chapter.
  • Validate a code’s currency against the most recent CMS / CDC release.

Primary use cases: Medical coding QA, claims-validation pipelines, prior-authorization review (pairs with prior-auth-review skill and cms-coverage MCP), and reference lookup inside clinical-trial protocol drafting.

Notes

ICD-10 is the US baseline; some payers also require ICD-10-CM modifiers and external-cause codes. This MCP covers the core code set — confirm payer-specific modifier requirements separately. Does not include CPT or HCPCS — those are governed by separate code sets.
